Accrued expenses consist of the following:

The change in warranty accruals for the year ended December 31, 2025, primarily reflects repair costs incurred and adjustments to pre-existing warranty obligations. New material warranty charges incurred during 2025 were less than $0.1 million, which management considers immaterial to the consolidated financial statements. No new material warranty charges were incurred during 2024. 

Restructuring Activities:

Activity and liability balances related to restructuring costs for the years ended December 31, 2024 and 2025 are as follows:

The 2024 charges and ending liability balance at December 31, 2024 noted above for severance costs largely relate to an initiative within our ITDS segment related to the transition of our fuse operations to other existing sites and also within our ADRS segment related to the transition of certain manufacturing from our Glen Rock, Pennsylvania facility to other existing Bel sites. The new charges noted above for other restructuring costs relate to housing and social insurance costs associated with our fuse restructuring initiative within our ITDS segment. The balances in other restructuring costs in the table above as of  December 31, 2024 largely related to remaining liabilities associated with the Company's facility consolidation project in the PRC.

The balance of accrued restructuring costs at December 31, 2025 largely related to remaining liabilities associated with the Company's facility consolidation project in the PRC whereby two of our ITDS manufacturing sites were consolidated into a single new site. During 2025, the Company recorded a $3.2 million reversal of other restructuring costs as a result of a non-cash settlement of liabilities related to this same project.
